Former X Factor winner Alexandra Burke never weighs herself as she feels it "mucks with your brain".

The British songstress is famed for her curvaceous body, and is confident in her skin.

Speaking to new! magazine, the star explained: "I don't weigh myself. I go by dress size. Weighing yourself mucks around with your brain too much. I don't believe any woman should weigh herself. I think you should just work out, eat right and feel the difference.

She added: "I've never been the girl that says, 'I have to drop a dress size, I have to lose a stone.' I'm not really body conscious. I know I'm in the spotlight but I shouldn't need to be stressed about my body and I never have been."

24-year-old Burke has revealed how she keeps in shape.

She explained: "I usually go to the gym a few times a week but as I'm busy recording my album and my schedule is a bit all over the place, it's really tricky. So at the moment I'm working out at home on the Xbox. And I dance for a living."
